i suspect this valve is stuck open on my 2007 911S
whenever I work on it, and i remove the intake (filter box) and crack open the throttle body, or remove the throttle body, I get a strong Fuel vapor smell. even after weeks of the car sitting.
I do not have a code and I do not have issues filling with fuel or starting.

I had to have my evap vent solenoid replaced recently as well due to the P0441 code on my 07 997.1S. Replacing it solved my CEL but I think what caused it to fail was due to the Driven Injector Defender cleaner I used. Some people say you should use it once a year before an oil change but some also say to use it every couple of fuel refills if you run gas with ethanol. Well, I did use it a couple times in succession (after 2 or 3 refills), and I think it dislodged a bunch of crap from my fuel system and some debris ended up clogging the vent valve causing my trouble code. The problem only arose after I put in the injector cleaner. I think I’m only going to use the cleaner once a year now. LOL.
Question to the group: Would the evap vent failing cause a slight RPM drop at launch? I changed my MAF sensor and it seems to have fixed the issue that I was having, but I feel like the car still bogs a bit at launch....
Hence why I was running the Driven Injector Defender, I thought it was bad fuel or dirty injectors.
